Yeah because Russia controlling all of Ukraine's resources wouldn't be a big deal? Grain, rare Earth, oil and on and on.
If people think our country is defending Ukraine out sympathy for the people or some moral high ground you're mistaken. Ukraine being subjugated to Russia would be bad for business. Everything else is secondary.
The American people are a different story. But our Govt. doesn't really care about what we want. It's about money to the people at the top.
